What prime numbers when reversed are also prime?
Prime numbers that remain prime when their digits are reversed are called emirps. Some examples of emirps include 13 (31), 17 (71), 31 (13), and 37 (73). These numbers are interesting because both the original number and its reverse are prime numbers.

How many prime numbers between 1 and 8888888888888888888888888888888888888888888888?
To determine the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888, we can use the Prime Number Theorem. This theorem states that the density of prime numbers around a large number n is approximately 1/ln(n). Therefore, the number of prime numbers between 1 and 8888888888888888888888888888888888888888888888 can be estimated by dividing ln(8888888888888888888888888888888888888888888888) by ln(2), which gives approximately 1.33 x 10^27 prime numbers.
What are numbers that have 2 factors called?
Prime numbers like 2, 3, 5 and 7.
